I noticed they've changed the city around Spock, when he jumps off the floating platform thing.
The next shot of him falling remains the same, so the buildings suddenly change. Work in progress!
Maybe that means all the current-day looking cars, lorries and busses on the streets are gonna change, too.

I'm not sure there has been a change. I think i read they jump from platform to platform during that chase scene, so maybe they are different platforms in different areas.

Unlikely seeing as it's an identical angle.

The first image looks more complete with better post-processing, hopefully it's the final one.
